The receiving range between Control Unit and Receiver is approximately 30 metres indoors,
however many factors can affect the RF transmission and shorten the operating distance, e.g.
shielding by thick walls, foil back plasterboard, metal objects such as filing cabinets, general
RF interference, etc.
The range is generally large enough for most household applications, but it is advisable to test
the RF transmission from the intended control unit location to the receiver location before fixing
the control unit to the wall.
To check the RF reception, follow the following steps:
1. Press the
button on the Control Centre until the set temperature is higher than room
temperature by a few degrees.
2. Wait for a few seconds. The Burner on (heat call) indicator should appear on the bottom left of
the LCD on the Control Unit.
3. Check the green LED on the receiver unit – it should be lit.
4. Press the
button to adjust the set temperature to be lower than room temperature.
5. Wait for a few seconds, and the Burner on (heat call) indicator should disappear and the green
LED should switch off.
6. If at step 3 the green LED is not illuminated, press the The Reset on the control unit and try to
place the control unit closer to the receiver.
7. Repeat steps 1-5.
If you are unable to get a stable RF connection between the Receiver and Control Unit, check that
the Receiver is both switched on and has a mains supply (orange LED lit). If this isn't the problem
you can also alter the RF address code by following the "RF Address Code Setting" section of
this manual, and should then repeat steps 1 to 5 (note that the Reset button on the Control Unit
should be pressed after altering the address code).
